List processes that have been running more than 2 hours

How can I list processes, with a defined name, that have been running for more than 2 hours. This is what I have tried. ps -efo pid,comm,etime | grep 'process name' | awk '{print $3}' ---- This is for Solaris. Or can someone help how to create a script that will send an email with the process IDs if there are processes running longer than 2 hours.
